Golf ball

A golf ball comprising a golf ball body and a paint film formed on a surface of the golf ball body, wherein a base resin constituting the paint film includes a polyurethane obtained by a reaction between a polyol composition and a polyisocyanate composition, a molar ratio (NCO/OH) of an isocyanate group (NCO group) of the polyisocyanate composition to a hydroxyl group (OH group) of the polyol composition is 0.6 or more, and the paint film has an elastic modulus of 300 MPa or less, and

• wherein the polyol composition contains a urethane polyol including a polyether diol having a number average molecular weight ranging from 800 to 3,000 as a constituent component, a content of the polyether diol having the number average molecular weight ranging from 800 to 3,000 in the constituent component of the urethane polyol is 70 mass % or more, the urethane polyol further includes a triol as a constituent component, and a mixing ratio (triol/diol) of the triol to the polyether diol having a number average molecular weight ranging from 800 to 3,000 ranges from 0.2 to 6.0 in a mass ratio.
